The second V-four Yamaha 0W70 1983 bike also had the first aluminium "Deltabox " frame and a 17 inch front wheel. Rear suspension was of the "bottom-link" type, still used today. With this bike Kenny Roberts fought with Freddy Spencer many fantastic races and in the end Freddy just clinched the World Championship ahead of Kenny. Eddie Lawson became 4th on a similar machine.
